An Investigation in Properties of Active Sites for PtY/Al2O3

Abstract

Abstract: The catalytic reforming and active site properties for Pt/Al₂O₃ and PtY/Al₂O₃ were studied by using pulse microcatalytic reactor, TEM and poisoning technnique. The kinetic data of dehydro-genation of cyclohexane for the two catalysts were calculated. The determination of the total numbers of active sites (TNAS) for the catalysts shows that Ymakes TNAS increase. The correlation of the catalytic behavior with the particle size and the properties of active sites for the two catalysts has also been discussed here.

Key words: Reforming, Yttrium, Poisoning of catalyst
